Abstract: A photovoltaic electricity generation unit is disclosed. The photovoltaic electricity generation unit includes a power unit having at least one photovoltaic array configured to output DC electrical power. The photovoltaic array is foldably supported by a frame assembly. The frame assembly includes a base frame operatively associated with ground engaging elements to be portable by a user, a plurality of support members extending upwardly from the base frame, and a plurality of intermediate frames foldably mounted on the plurality of support members. A control unit having a controller accommodated inside a housing mounted on the frame assembly is configured to receive the DC electrical power from the power unit and output AC electrical power to the load system.
